Interface Solid State Relays

In addition to panel-mount or Din-Rail mount Solid State Relays, celduc® relais offers compact and modular interface relays.

What is an interface SSRs ?

Interface technology means separating, forming, processing, converting and adapting signals.

Interface relays are special types of electrical relays that ensure the safe and reliable transmission of signals to automation systems. This interfacing is crucial for the proper functioning of automated systems.

In modern automation, the control element is a computer or an automation system connected to the process by a multitude of wires leading to sensors or actuators. These high-performance processors in their domain are sensitive to interference and surges from the industrial environment. Additionally, their operating range is often limited to 24 VDC / 100 mA in voltage and current.
In order to achieve voltage/current adaptation and galvanic isolation, it is necessary to interface them with elements ensuring these functions while transmitting the logical input and output orders while protecting against industrial disturbances.

This is possible thanks to our range of interface relays. The relay is placed between your control system and your equipment to ensure safe switching.

What are the main benefits of interface relays ?

Interface Solid State Relays are used in demanding industrial applications :

• Safe and reliable galvanic isolation, voltage conversion & circuit multiplication
• Highest contact ratings
• PCB or socket mounting
• Compatible with electromechanical relays
• AC or DC outputs
• Suitable for all load types
• High I/O isolation (≥4000V)

Typical applications

This line of interface relays is designed to fit a wide range of industrial applications. We have solutions for almost all application needs.

Here are some examples of applications :

• Reduced PLC outputs to meet energy consumption goals
• Switching currents or voltage too high for PLC outputs to handle
• Interfacing two or more system voltages – for example, 24V to 120V
• Controlling multiple loads from safety and interlock commands
• Reduced PLC outputs by using relays to turn many devices on and off simultaneously
